Hello, friends.. 

I am implementing MapView in my application..

I am using below code for MapView..

MapView 
{
  id: mapView
  horizontalAlignment: HorizontalAlignment.Fill
}

 I also added import bb.cascades.maps 1.0 & given permission GPS Location, Location  in bar-descriptor.xml

When I run application I can see only black screen.

I got below error in device log.

There is a good example in github on how to use the MapView.

https://github.com/blackberry/Cascades-Samples/tree/master/custommapview

I know that the MapView does not work if you use WiFi without a SIM card and your firewall blocks unusual ports. Maybe using a SIM card solves the problem. Or there is an error in your code. Then the github example should be a good starting point.

You have to change the altitude. That's a value in meters on how far the camera is above the ground. You can find it in the documentation.

altitude: 10000

Documentation: https://developer.blackberry.com/cascades/reference/bb__cascades__maps__mapview.html

[oliver_kranz]

Yes, if the connection works then setting the altitude is a solution.

I set altitude: 10000, still map is not appear in device. I can see only white screen..

I found below error in Console

eglSwapBuffers: an EGLSurface argument does not name a valid surface configured for rendering

WindowToWorld: lat=0.000000 lon=0.000000
centerX=384 centerY=514

Hi,

Im currently testing on mapview as well. Does the mapview only can be tested on device and not simulator? Just wanna confirm this.

Thank you.

I have read in other posts that BB Maps does not work in the simulator. Don't know why, because other mapping solutions work fine in the simulator.

[steve8820]

Yes. Thats what i understand too. But what kind of other mapping solutions you mentionaing? Im interested on other options instead of mapview.

[jtegen]

Other solutions are using a WebView to use with HTML based map providers (e.g. Google, MapQuest), or you create your own SDK like we did (not Cascades).

Thanks for the solution. Will try this alternative.
